Subaru Legacy BN/BS (2015-2019) Service Manual: Diagnostics with phenomenon inspection

1. DOES NOT CONTROL HEADLIGHT BEAM AXIS

CAUTION:

Before performing diagnosis, check the fuse in this circuit.

Initialization is required after replacing the SRF CM.

1.CHECK CURRENT DATA.

Display {ECU ACC} using Subaru Select Monitor.

Does the current data indicate the standard value-

2.CHECK HARNESS BETWEEN IG POWER SUPPLY — SRF CM.

1) Disconnect the SRF CM connector.

2) Turn the ignition switch to ON.

3) Measure the voltage between SRF CM connector and chassis ground.

Repair or replace the harness.

3.CHECK INDICATOR OUTPUT.

Turn the ignition switch to ON.

Does the warning indicator turn on for three seconds-

4.CHECK CURRENT DATA.

1) Display «Indicator Signal» using Subaru Select Monitor. Read Current Data

2) Turn the ignition switch to ON.

Is it set as ON for 3 seconds-

Check the combination meter. Basic Diagnostic Procedure > PROCEDURE

Replace the SRF CM. Steering Responsive Fog Lights CM

5.CHECK INDICATOR OUTPUT.

Leave the ignition switch to ON for 10 seconds.

Does the warning indicator light go off-

6.CHECK HEADLIGHT ASSEMBLY (ACTUATOR) DRIVE.

1) Connect the SRF CM connector.

2) Turn the ignition switch to ON, and within 10 seconds, repeat the OFF > Low beam of headlight switch 5 times.

3) Check that the headlight beam drops once, then returns to normal.

4) Then, after waiting for 30 seconds or more with the ignition ON, turn the ignition switch to OFF.

Does the headlight beam drop down once, and then return-

7.CHECK HEADLIGHT ASSEMBLY (ACTUATOR) OUTPUT.

1) Display «Actuator Signal» using Subaru Select Monitor. Read Current Data

2) Turn the ignition switch to ON, and within 10 seconds, repeat the OFF > Low beam of headlight switch 5 times.

3) Check that the headlight beam drops once, then returns to normal.

4) Then, after waiting for 30 seconds or more with the ignition ON, turn the ignition switch to OFF.

Does the current data indicate the standard value- (Does the value change at 10 — 90%-)

Diagnostics with Phenomenon > INSPECTION

Replace the SRF CM. Steering Responsive Fog Lights CM

8.CHECK OUTPUT VOLTAGE BETWEEN HEADLIGHT ASSEMBLY (ACTUATOR).

1) Disconnect the SRF CM connector.

2) Turn the ignition switch to ON.

3) Measure the voltage between SRF CM connector and chassis ground.

Connector & terminal

(B42) No. 16 (+) — Chassis ground (−):

Is the voltage 8 — 16 V-

Replace the headlight assembly. Headlight Assembly
